ENVELOP-REGISTERING MECHANISM FOR ENVELOP-MACHINES.

Specification of Letters Patent.

'latcnted All". 29, 1916.

Application filed August 19, 1915. Serial No. 46,280.

T 0 all whom it may concern Be it known that I, JOHN J. ()(/oNxi:LL, a citizen of the United States, residing at Dayton, Montgomery county, and State of Ohio, have invented certain new and useful Improvements in Envelop-Registoring Mechanism for Envelop-Machines, of which the following is a full, clear, and exact descrip tion.

This invention relates to certain new and useful improvements in machines for making envelops and is particularly adapted for use in continuous rotary machines in which, a sevries of envelop blanks are fed through the machine and fabricated by means of folding, gumming and printing operations into a complete envelop. In such machines it is important that the register of the blank or partially completed envelop be correct before certain further operations are per formed. This correct register is necessary in order that the printing and gmmning operations be performed on the proper place on the envelop. To obtain exact register I have found that a certain arrangement of register pins and rollers will correctly aline each envelop and allow it to feed forward at the proper time to subsequent devices such as gummers or printers.

Inthe drawing Figure 1 shows an end view of the register rolls and register pins and also shows the path of an envelop as it approaches and leaves the registering devices. Fig. 2 shows a top plan view of the register roll and register pins with an envelop in position on the pins. Fig. 3 shows a detail view of the cam mechanism to operate the register pins. Fig. 4 shows another detail view of the cam mechanism shown in Fig. 3 with the parts in a different position.

In Fig. 1 the envelop advances from preceding mechanism along line 10 in the direction of the arrow. It eventually enters the bight of envelop feeding rolls 11 and 12 and is delivered from these rolls in proper register and at the proper time to subsequent mechanism. The envelop leaving the rolls advances in a path tangential to the rolls as along the line 13.

In Fig. 2 the dotted lines 14 and 15 show the forward edge of the envelop and indicate the position that the envelop may have assumed in advancing to the rolls 11 and 12. This figure also shows an envelop 16 in the proper position to enter the bight of the rolls. In order to position the envelop from the received position I. 0. ll or 15 to correct position 1 I employ register pins 17 and 18. These pins project outwardly a considerable distance from the periphery of roll 12 and are adapted to engage the envelop and allow it to settle to proper position before passing into the bight of rolls 11 and 12. To. insure the envelop settling correctly and to exactly time the advancing of the envelop into the bight of the rolls 11 and 12 I employ certain mechanism which will now be described.

The register pins 17 and 18 are secured to a shaft 15) and project outwardly therefrom through slots 20 in rollers 12. The shaft 19 extends through roller to the right and through a hollow shaft 21 which forms one siqiporting shaft for the roller 12. Hollow shaft 21 is journaled in a boss in a side frame 22 of the machine. Shaft projects from the opposite side of roller 12 and is similarly journaled in a boss in side frame 22. This shaft projects beyond the side frame and carries a gear or other driving device (not shown) for turning the shafts 21 and 23 and roller 12. In order to provide clearance for the points of pins 17 and 18 so that they may pass roller 11 this roller is cut away as shown at See Fig. 1. Roller 11 is supported on a shaft 40 which is journaled in the side frames 22 and driven by gearing (not shown) or other driving mechanism at the same speed as roller 12. The register pins 17 and 1S normally rotate in unison with roller 12. Just before the envelop reaches the bight of rolls 11 and 12 these pins are given a rearward movement with respect to advancing rotation of rolls 12. This gives the envelop time to settle into proper alinement on the register pins and accurately times the gripping of the envelop between the rolls 11 and 12. After the envelop passes into the bight of rolls 11 and 12 the pins 17 and 18 are advanced relatively to roll 12. This advancing movement of the pins removes them to a position in which they will not interfere with the advancing front edge of the envelop as it emerges from the rolls 11 and 12.

To impart the above mentioned relative movement to the pins I employ the following mechanism: The hollbw shaft 21 is extended through the boss ion the side frame 22 and carries on its outer end an arm 25.

\ A short shaft 26 is pivotally mounted in this arm and this shaft carries on one end the arm 27 and on the other the arm 28. Arm 26 carries a stud 29 which supports a cam roller 30 which cooperates with the register pin operating cam 31 which is fixed to the boss on the side frame 22 of the machine. A side View of this cam is shown in F' 7 5 and 4 and it will be seen that it has a gradiially increasing throw at 32 and that heyond the peak of the cam the cam surface falls in straight line which has the effect of causing a gradual lift and a quick return of the cam follower roller 30. On the rotation of hollow shaft 21 arm carries the shaft 26, arm 27, stud 29 and roller follower 30 around the fixed cam and the fixed cam imparts a rocking movement to the shaft 26.

The shaft 19, which carries the register pins, extends through the hollow shaft 21 fixedcam 31 and arm 25 and carries on its end a bifurcated arm 34. Engaging the slot in said bifurcated arm is a roller 35 which is carried on a stud 36 which. projects inwardly from the arm 28 carried on shaft 26. In order to hold the register pins 17 and 18 in forward position in the slots 20 and to hold the roller follower 30 in contact with .the fixed cam 31 I employ a tension spring 37 which is secured to a post 38 attached to arm 34 on shaft 19. The opposite end of this springis attached to a post 39 which is attached to the arm 25 on hollow shaft 21.

The operation of the device is as follows:

The envelop advances along the line 10 (Fig. 1) and eventually contacts with the register pins 17 and 18 which are in the position shown in Figs. 1 and 3. These pins arrest the envelop and just before the envelop reaches the bight of the rolls 1]. and 1-3 the register pins are given a slight rclativc rearward movement by fixed Gain 31. The fol lower 30 rides up on the side 32 of ram Ill) and thereby rocks shaft 26 and through arm 28, stud 36 and roller 35, rocks the bifurcated arm 34 in a clockwise dircetioa 3ifurcated arm 34 being attached to shaft [8 moves the register pins 17 and 125, in a clockwise direction in slot 20 ai id thereby alines the envelop properly. The positiop of hiTrts when the pins 17 and 18 are in. rocked posi tion is shown in Fig. 4. The envelop then passes into the hight of rolls 11 and 12 at a definite time period since the pins 17 and 18 have caused the envelop to be advanced into the rolls at the exact time the rear edge of the pins passes the line of centers of rolls 11 and 12. The pins pass into the cut away parts 24 of roll 11 and shortly after they pass the line of centers of rolls 11 and 12 the follower 2O rides down the abrupt face of cam 31. The follower living drawn to contact With the cam by means of the spring 37. This serves to rock shaft 11) in acoun ter-clockwise'direction and restores the pins 17 and 18 to their normal position in the forward portion of slots 20. When the pins are in this position (shown in Fig. 3) the envelop can emerge from rolls 11 and 12 in a path which is substantially tangential to the periphery of the cylinders or rolls. (see Fig. 1) and can trawl forward in this path without ontacting with the pins and when dclimred to the suhscqucnt mcchanism its registry and timing will be correct. *5
